What are some good workarounds to get typeform-like signup UX + recurring stripe payment setup?

I'm working on Checkout Page (https://checkoutpage.co) and am looking for good reasons to add recurring billing. I can imagine something like filling in a Typeform -> link to Checkout Page -> return to a certain URL after subscribing.

Yeah, it is a bummer that TypeForm doesn't support subscriptions. Also, when a customer makes a purchase in Stripe, TypeForm doesn't create a customer in your stripe account. For example, I've made over 500 sales via TypeForm, and my Stripe account shows 0 customers.

And if you don't need a complex multi-step questionnaire like you'd be able to create using TypeForm or PaperForm, if you just need something simple that can handle recurring billing, here's a good option:
